When doctors suggest bed rest for patients with lumbar disc herniation, patients often have great doubts about it: can simply lying in bed cure lumbar disc herniation? In fact, bed rest is a traditional and effective method of treating lumbar disc herniation. The lumbar disc pressure is highest in the sitting position, intermediate in the standing position, and lowest in the lying position. Bed rest can remove the pressure of weight on the disc, and braking can relieve the extrusion of the disc by muscle contraction and ligament tension, so as to facilitate the recovery of the disc height and the retraction of the herniated nucleus pulposus; it can avoid the wear and tear brought about by the movement of the lumbosacral nerve roots in the spinal canal during exercise. Degenerative changes of the lumbar spine are inextricably linked to weight-bearing. Strict and scientific bed rest firstly removes the main factors that make the lumbar spine lesions develop further and creates the necessary conditions for the recovery of the disease. When lumbar disc herniation develops, the local soft tissues have different degrees of strain, aseptic inflammation and muscle spasm, and a large amount of lactic acid, histamine, CO2 and other pathogenic substances accumulate in the tissues, stimulating sensory nerve fibers and producing pain. Lying on a padded wooden bed can make the soft tissues of the lumbar region get sufficient relaxation and rest, relieve muscle spasm, promote blood circulation and transport away pain-causing substances, which can obviously reduce pain and restore function. In addition, after traction or tui-na treatment, bed rest is generally needed for a period of time to consolidate the therapeutic effect. In short, bed rest is the basis of non-surgical treatment.
